OSCAR CHARLES 'ROESEN, OFBROOKLYN, NEW YORK, ASSIGNOR TO WOOD N VMACHINERY CORPORATION, or New YORK, N; Y., A CORPORATION or VIRGINIA jPARALLEL-ADJUSTMENT non roLmNe COUPLES Application filed June 27,1928,'Seria1 No. 288,613. Renewed April 29, 1931.

The principal object of this invention is to provide means whereby thetwo journals of one of the cylinders constituting .a folding couple fora paper folding .machinecan be adjusted equally and are necessarilysoadjusted. Anotherobject is to provide. a construction for performingthis adjustment in which the amount of the" adjustment can be readeasily ona scale, thus eliminating the hand method of'adj ustment nowemployed individually at each end of. the cutting cylinder and avoidingthe necessity of meatsuring the distance between the two cylinders .fordifferent sizes of the folded product.

Other objects and advantages :of the'finvention will appear hereinafter.

Reference is to he had to the accompanyingdrawings in which 5- Fig. lisa plan of arfolding couple showing a preferred form of this invention;

Fig. 2 is :an end view .of the same; 1

Fig. 3 isa sectional view n the line 33 Fig.4 isa plan of-famodification;

Fig. 5 is an end view thereof; I Fig. 6 is a plan ofathird'form, and

Fig. 7 is an end view of the same.

In the form shown in Figs. 1, 2 and 3,-the folding cylinder 10 .is ofthe usual construction, cooperating withxthe folding rolls 11 and havingfolding blades 12. Thecutting cylinder 13 cooperates with thefol'ding'cyL' inder as usual. I

It will be obvious that when various sizes of newspapers are run throughthefolder, the space between the folding-and cutting cylinders has to.bealteredr It is considerably less for a sixteen page'paper for examplethan fora sixty four page paper...

One of the cylinders, .preferablynthe cutting cylinder, is mounted onpillow blocks 14:. It is the ordinary procedu're to move the pillowblocks at each end supporting the journals of the cutting-cylinderinorder to secure the desired adjustment. The pressman has to adjusteach pillow block independcntly and hasto measure the'space between thecylinders 10and-13jby gauges or feelers to ascertain when hehas theright adjustment; Thenfhe has-totighten up bolts on eachend and becarefulthatthe' a just ment is not lost while doing it. It isonly by theuse of the gauges or feelers at each end that he can be sure that thetwo cylinders are left in parallel condition. In the form shown in Figs. 1 2 and 3, the ]Ol1I'11ELlS or studs of the cutting cylinder aremounted in eccentric boxes 17 which constitute movable supports for-thecutting cylinder. Obviously these boxes will move the ournals. The. factthat they may raise the ournals or lower them a little is notim-.portant in this 'kind' of, a machine. These eccentric boxes areoriginallyset alike'and each one is equipped with a segmental worm 1B5wheel 18. These two worm wheels are operated by segmentalworms 19located-on parallel shafts 20 arranged in suitable bearings and'each oneprovided with a worm wheel 21 and one of them with a circular graduated.dial 22 whichcooperates with a zero point 23 on the bearing instationary. position.

The two worm wheels 21 mesh with; two worms 24f on an operating shaft 25having a hand wheel 26. Obviously the turning of the hand wheel 26 willadjust both bearingsin the same manner and to the same degree and theamount will be indicated onthe 'dial22. In the form shown in Figs.411I1d5, the method is quite similar, the pillow blocks are-employed inthe same Way,.but they are themselves adjustable, constituting movablesupports. They are provided withslots15 wide enough to allow for theadjustment. of the blocks "in spite of the holding bolts 16. Each one isheld in place by an adjusting screw 30, these two screws being parallel;By gears 31 they are connected with an operating shaft 32 having a handwheel 33 for operating it; This hand wheel itself is provided withacirc'ular gauge or graduated area 34 and a stationary pointer 35 ismounted on the bearing. This constitutes simple means for accomplishingthe same result as in Figs. 1, 2 and 3. Referring now to Figs. 6 and'7,.I have shown the sliding pillow blocks 14 of the same kind as beingadjusted by a wedge 36 for each one. The two wedges are connected'by athreaded rod 87 which passes through both of them and has two screwthreads of the same hand. This rod is provided with a pinion 38 meshingwith a gear 39 equipped with a handle 40. The turning of this gear bythe handle will turn the rod 37 and move the wedges in or out to adjustthe two pillow blocks. The gear is provided with a dial 41 cooperatingwith a stationary pointer 42 for the purposes previously described.Another pair of wedges 43 are employed having a similar adjusting screw44 for the purpose of jamming up the wedges 36 to eliminate allback-lash from the pillow blocks. 7

In all the forms shown, the same general result is secured, adjustingboth supports simultaneously and equally, thereby maintainingparallelism between the cutting and folding cylinders and providing anindicator calibrated forthe purpose of showing the space left betweenthe cylinders.

Although I have illustrated and described only three forms of theinvention, I am aware of the fact that other modifications can be madetherein by any person skilled in the art without-departing from thescope of the invention as expressed in the claims. There fore, I do notwish to be limited to all the details of construction herein shown anddescribed, but what I do claim is:

1. The combination with a folding couple comprising a folding cylinderand a cutting cylinder, of movable supports at each end of one of saidcylinders, and means for simultaneously moving the two end supportstoward or from the other cylinder at equal speeds and a graduated dialoperated by said last mentioned means for showing the adjustment.

2. The combination with a pair of cylinders and a pair of pillow blocks,of eccentric boxes carried by the pillow blocks for supporting theopposite ends of one of the cylinders,-wh.ereby the turning of saidboxes will move the cylinder toward or from the other cylinder, and ashaft extending across the machine having means for simultaneouslyturning the two eccentric boxes.

3. The combination with a pair of cylinders and a pair of pillow blocks,of eccentric boxes carried by the pillow blocks for supporting theopposite ends of one of the cylinders, whereby the turning of said boxeswill move the cylinder toward or from the other cylinder, a wheelsegment connected with each of said boxes, a worm for operating eachsegment, a shaft on which each worm is mounted, said shafts beingparallel with each other, and a shaft extending across the machinehaving means for simultaneously turning the first named shafts equaldistances in the same time. 7

4. The combination with a folding couple comprising a folding cylinderanda cutting cylinder, of movable supports at each end of one of saidcylinders, means for simultaneously moving the two end supports towardor from the other cylinder at equal speeds,

and means for measuring and indicating the distance between thecylinders.

5. The combination with a folding couple comprising a folding cylinderand a cutting cylinder, of two movable means for supporting the journalsof the cutting cylinder, a shaft, means connected with said shaft forsimultaneously and equally moving the two movable means toward or fromthe folding cylinder, and a graduated dial operated by said shaft forshowing the adjustment.

6. The combination with a folding couple comprising a folding cylinderand a cutting cylinder, of a pair of pillow blocksmovably mounted forsupporting one of said cylinders, a shaft extending across the machineparallel with the axes of said cylinders, ahandle for turning said shaftby hand, means at opposite ends of the shaft formoving the two pillowblocks simultaneously and equally to adjust the distance between thecylinders and keep their axes parallel and a graduated dial operated by.said last mentioned means for showing the adjustment.

'7. The combination with a folding couple comprising a folding cylinderand a cutting cylinder, of a pair of pillow blocks movably mounted forsupportingsaid cutting cylinder, a shaft parallel with the axes of saidcylinders, a handle for turning said shaft by hand, means at oppositeends of the shaft for moving the two pillow blocks simultaneously andequally tov adjust the distance between the cylinders and keep. theiraxes parallel, a rotary dial connected with the shaft and a stationarypointer for showing the exact adjustment.

8. The combination with a printing couple, of a pair of laterallyadjustable pillow blocks for supporting the cutting cylinder thereof,transverse screws for adjusting said pillow blocksback and forth, ashaft extending across the machine, a hand wheel on the shaft forturning it, and means for rotating the two screws from the shaftsimultaneously and equally. i

9. The combination with a folding couple comprising a cutting cylinderand a folding cylinder and a pair of pillow blocks adjustably mountedfor supporting the cutting cylinder, of a pair of wedges for moving thetwo pillow blocks, a shaft having screw-threaded connection with thetwo. wedges, whereby when the shaft is turnedthe two wedges will moveforward or back equal distances, and means for turning said shaft.
